How to Calculate 1.5 OT Rate

Calculating overtime pay, commonly referred to as "time and a half," is a fundamental skill for both employers and employees to ensure fair compensation. Under the Fair Labor Standards Act (FLSA) in the United States, non-exempt employees must receive overtime pay for hours worked over 40 in a workweek at a rate not less than one and one-half times their regular rate of pay.

The 1.5 OT Rate Formula

The math behind a 1.5 OT rate is straightforward. You take your regular hourly wage and multiply it by 1.5.

Regular Hourly Rate × 1.5 = Overtime Hourly Rate

Step-by-Step Calculation Example

Let's say you earn $20.00 per hour and you worked 45 hours this week (5 hours of overtime).

  1. Calculate the 1.5 Rate: $20.00 × 1.5 = $30.00 per hour.
  2. Calculate OT Pay: $30.00 × 5 hours = $150.00.
  3. Calculate Regular Pay: $20.00 × 40 hours = $800.00.
  4. Total Gross Pay: $800.00 + $150.00 = $950.00.

Key Considerations

  • Workweek Definition: Overtime is typically calculated on a fixed 7-day workweek, not bi-weekly or monthly periods.
  • Non-Discretionary Bonuses: In some jurisdictions, bonuses must be included in the "regular rate" before multiplying by 1.5.
  • Double Time: Some states or specific union contracts might require "double time" (2.0x rate) for holidays or working over 12 hours in a single day.
